value Previous active scene and the new active scene.

Descripción

Subscribe to this event to get notified when the active Scene has changed.

This script added to activeSceneChanged takes two hidden arguments. These are the replaced Scene and the next Scene. The arguments are not visible.

In the Editor this event is sent only in Play mode (not in Edit mode). If the event is needed for Edit mode then use EditorSceneManager.activeSceneChanged.

// SceneManager.activeSceneChanged
//
// This example configures Scene1 to wait for 1.5 seconds before switching to Scene2.
// Scene1 is the replaced scene; Scene2 is the new loaded scene.

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;

public class ScriptExample1 : MonoBehaviour { public delegate void Change(); public static event Change TimeChanged;

public void Start() { SceneManager.activeSceneChanged += ChangedActiveScene;

// wait 1.5 seconds before change to Scene2 StartCoroutine(TimeChangedScene()); }

IEnumerator TimeChangedScene() { print(Time.time); yield return new WaitForSeconds(1.5f); print(Time.time);

// call the event TimeChanged(); }

private void ChangedActiveScene(Scene current, Scene next) { string currentName = current.name;

if (currentName == null) { currentName = "Replaced"; }

Debug.Log("Scenes: " + currentName + ", " + next.name); }

void OnEnable() { Debug.Log("OnEnable"); ScriptExample.TimeChanged += ChangeScene; }

void ChangeScene() { Debug.Log("Changing to Scene2"); SceneManager.LoadScene("Scene2");

Scene scene = SceneManager.GetSceneByName("Scene2"); SceneManager.SetActiveScene(scene); }

void OnDisable() { ScriptExample.TimeChanged -= ChangeScene; Debug.Log("OnDisable"); } }

ScriptExample2 simply announces that this is the active scene.
